Description

Technical Field

[0001] This utility model relates to the field of pyrolysis technology, specifically to a pyrolysis furnace. Background Technology

[0002] A pyrolysis furnace is a reaction device that decomposes solid substances into gaseous, liquid, and solid substances through thermochemical conversion. Its core principle is to use high temperatures (usually 300~800°C) in an oxygen-free or low-oxygen environment to break the chemical bonds of organic matter, generating gaseous, liquid, and solid substances.

[0003] When materials are pyrolyzed in a pyrolysis furnace, the materials are stacked in the pyrolysis chamber. The thermal resistance effect of the stacked materials makes it difficult for heat to penetrate, resulting in only partial pyrolysis of the inner layer materials instead of complete decomposition into small molecule gases, leading to low pyrolysis efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a pyrolysis furnace to solve the problem mentioned in the background art, where, when pyrolyzing materials in a pyrolysis furnace, the materials are stacked in the pyrolysis chamber, and the thermal resistance effect of the stacked materials makes it difficult for heat to penetrate, resulting in only partial pyrolysis of the inner layer materials instead of complete decomposition into small molecule gases, leading to low pyrolysis efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pyrolysis furnace, comprising a furnace body and a stirring unit:

[0006] The furnace body has a combustion chamber and a pyrolysis chamber inside. A heat-conducting plate is installed between the combustion chamber and the pyrolysis chamber. The stirring part is located inside the furnace body and is used to stir the material in the pyrolysis chamber to promote the full pyrolysis of the material. The stirring part has a vertically rotating frame installed inside the pyrolysis chamber. The top of the rotating frame extends to the outside of the furnace body and has a connection port. The rotating frame has a gas guide channel inside and a gas outlet on the side. The gas outlet is connected to the connection port through the gas guide channel. The rotating frame rotates to stir the material inside the combustion chamber.

[0007] By adopting the above technical solution, the material in the pyrolysis chamber can be heated more evenly under the stirring of the rotating frame. The heat from the combustion chamber conducted by the heat conduction plate can be fully applied to the material, improving the efficiency and effect of material pyrolysis. At the same time, the external gas supply equipment can deliver necessary gases, such as pyrolysis aid gases, into the pyrolysis chamber through the connection port, gas guide channel and gas outlet, further promoting the pyrolysis process of the material.

[0008] Preferably, the furnace body also has an exhaust port located on the side of the furnace body, which is connected to the pyrolysis chamber. Both the combustion chamber and the pyrolysis chamber have openable closed doors on their sides via a rotating structure.

[0009] By adopting the above technical solution, the waste gas generated during the pyrolysis process in the pyrolysis chamber can be discharged from the furnace body through the exhaust port in a timely manner, ensuring a stable gas environment in the pyrolysis chamber, which is conducive to the continuous progress of the pyrolysis reaction. Moreover, the openable and sealable doors on the sides of the combustion chamber and the pyrolysis chamber facilitate the operation of operators to add fuel to the combustion chamber and add materials to be pyrolyzed to the pyrolysis chamber, and also facilitate the inspection and cleaning of the furnace body.

[0010] Preferably, the furnace body also has a support frame disposed inside the pyrolysis chamber, and the bottom of the rotating frame passes through the support frame and is rotatably connected to the support frame.

[0011] By adopting the above technical solution, a stable support can be provided for the rotating frame, enabling it to rotate smoothly within the pyrolysis chamber. The rotating connection between the support frame and the rotating frame ensures both the flexibility of the rotating frame's rotation and prevents it from swaying or shifting during rotation, thus ensuring effective stirring of the materials within the pyrolysis chamber.

[0012] Preferably, the stirring part also has a transmission tooth a disposed on the top side of the rotating frame, a power tooth is rotatably disposed on the top of the furnace body, a motor is disposed on the top of the power tooth, the output end of the motor is connected to the power tooth, and the power tooth is meshed with the transmission tooth a.

[0013] By adopting the above technical solution, an electric motor can be used as a power source. The power output by the motor is transmitted to the transmission gear a through the power gear, thereby driving the rotating frame to rotate in the pyrolysis chamber.

[0014] Preferably, the air outlet is located around the side of the rotating frame, and the connection port is connected to an external air supply device via a hose.

[0015] By adopting the above technical solution, the gas delivered from the external gas conveying equipment can be evenly diffused into various positions in the pyrolysis chamber through the connection port and the gas guide channel, and then through the surrounding gas outlet. This ensures that the gas distribution in the pyrolysis chamber is uniform, allowing the material to fully contact the gas and further promote the pyrolysis reaction of the material.

[0016] Preferably, the stirring part also has a rotating scraper nested on the side of the rotating frame, which abuts against the air outlet.

[0017] By adopting the above technical solution, the rotating scraper will move relative to the rotating frame as it rotates. Since the rotating scraper is in contact with the air outlet, it can promptly scrape away any material residue that may accumulate around the air outlet, preventing the air outlet from being blocked.

[0018] Preferably, the stirring part also has a transmission tooth b disposed on the top of the rotating scraper, and the inner wall of the pyrolysis chamber is surrounded by annular retaining teeth, which mesh with the transmission tooth b.

[0019] By adopting the above technical solution, when the rotating frame rotates, the meshing action of the transmission tooth b and the ring clamp tooth can be used to make the rotating scraper generate relative rotational motion relative to the rotating frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a stirring part, the material in the pyrolysis chamber can be heated more evenly under the stirring of the rotating frame. The heat from the combustion chamber conducted through the heat conduction plate can be fully applied to the material, improving the efficiency and effect of material pyrolysis. At the same time, the external gas supply equipment can deliver necessary gases, such as pyrolysis aid gases, into the pyrolysis chamber through the connection port, gas guide channel and gas outlet, further promoting the pyrolysis process of the material.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a pyrolysis furnace, including a furnace body 1 and a stirring unit 2.

[0031] The furnace body 1 has a combustion chamber 101 and a pyrolysis chamber 102 inside. A heat-conducting plate 103 is provided between the combustion chamber 101 and the pyrolysis chamber 102. A stirring part 2 is located inside the furnace body 1 to stir the material in the pyrolysis chamber 102 to promote the complete pyrolysis of the material. The stirring part 2 has a rotating frame 201 that is vertically rotatably installed inside the pyrolysis chamber 102. The top of the rotating frame 201 extends to the outside of the furnace body 1 and has a connection port 202. A gas guide channel 203 is provided inside the rotating frame 201, and a gas outlet 204 is provided on the side of the rotating frame 201. The outlet 204 is connected to the connection port 202 through the air guide 203. The rotating frame 201 rotates to agitate the material inside the combustion chamber 101, which can make the material in the pyrolysis chamber 102 more evenly heated under the agitation of the rotating frame 201. The heat from the combustion chamber 101 conducted through the heat conduction plate 103 can be fully applied to the material, improving the efficiency and effect of material pyrolysis. At the same time, the external gas supply equipment can deliver necessary gases, such as pyrolysis aid gases, into the pyrolysis chamber 102 through the connection port 202, the air guide 203 and the outlet 204, further promoting the pyrolysis process of the material.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a pyrolysis furnace, including a stirring section 2, a rotating frame 201, and a rotating scraper 208.

[0034] Exhaust ports 104 are arranged on the side of the furnace body 1, and the exhaust ports 104 are connected to the pyrolysis chamber 102. The sides of the combustion chamber 101 and the pyrolysis chamber 102 are equipped with openable closed doors through a rotating structure, which can promptly discharge the waste gas generated in the pyrolysis process in the pyrolysis chamber 102 into the furnace body 1 through the exhaust ports 104, ensuring a stable gas environment in the pyrolysis chamber 102, which is conducive to the continuous progress of the pyrolysis reaction. Moreover, the openable closed doors on the sides of the combustion chamber 101 and the pyrolysis chamber 102 facilitate the operation of operators to add fuel to the combustion chamber 101 and add materials to be pyrolyzed to the pyrolysis chamber 102, and also facilitate the inspection and cleaning of the inside of the furnace body 1.

[0035] A support frame 105 is fixedly installed inside the pyrolysis chamber 102. This fixing method is a conventional detachable fixing method, such as bolt connection or snap-fit ​​connection. The bottom of the rotating frame 201 passes through the support frame 105 and is rotatably connected to it, providing stable support for the rotating frame 201 and allowing it to rotate smoothly within the pyrolysis chamber 102. This rotatable connection between the support frame 105 and the rotating frame 201 ensures both the flexibility of the rotating frame 201's rotation and prevents it from swaying or shifting during rotation, thus ensuring effective stirring of the materials within the pyrolysis chamber 102.

[0036] A transmission gear a205 is integrally provided on the top side of the rotating frame 201, and a power gear 206 is rotatably provided on the top of the furnace body 1. A motor 207 is provided on the top of the power gear 206, and the output end of the motor 207 is connected to the power gear 206. The power gear 206 and the transmission gear a205 are meshed and connected. The motor 207 can be used as a power source. The power output by the motor 207 is transmitted to the transmission gear a205 through the power gear 206, thereby driving the rotating frame 201 to rotate in the pyrolysis chamber 102.

[0037] The gas outlet 204 is arranged around the side of the rotating frame 201. The connection port 202 is connected to the external gas conveying equipment through a hose. The gas delivered from the external gas conveying equipment can pass through the connection port 202 and the gas guide channel 203, and then diffuse evenly into various positions in the pyrolysis chamber 102 from the surrounding gas outlet 204. This ensures that the gas distribution in the pyrolysis chamber 102 is uniform, so that the material and the gas can fully contact each other and further promote the pyrolysis reaction of the material.

[0038] A rotating scraper 208 is nested and rotatably mounted on the side of the rotating frame 201. The rotating scraper 208 abuts against the air outlet 204, and can move relative to the rotating frame 201 as the frame rotates. Because the rotating scraper 208 abuts against the air outlet 204, it can promptly scrape away any material residue that may accumulate around the air outlet 204, preventing the air outlet 204 from becoming blocked.

[0039] A transmission tooth b209 is integrally provided on the top of the rotating scraper 208, and an annular retaining tooth 210 is arranged around the inner wall of the pyrolysis chamber 102. The annular retaining tooth 210 is meshed with the transmission tooth b209. When the rotating frame 201 rotates, the meshing action of the transmission tooth b209 and the annular retaining tooth 210 can cause the rotating scraper 208 to rotate relative to the rotating frame 201.

[0040] Working Principle: First, the operator opens the operable doors on the sides of the combustion chamber 101 and the pyrolysis chamber 102, adds fuel into the combustion chamber 101, and adds the material to be pyrolyzed into the pyrolysis chamber 102, then closes the doors. Next, the fuel in the combustion chamber 101 is ignited. The heat generated by the combustion of the fuel is conducted to the pyrolysis chamber 102 through the heat conduction plate 103, providing the necessary thermal energy for the pyrolysis of the material. At the same time, the motor 207 is started, and the motor 207 outputs power to drive the power gear 206 to rotate. Since the power gear 206 is meshed with the transmission gear a205 on the top side of the rotating frame 201, the rotation of the power gear 206 will drive the rotating frame 201 to rotate within the pyrolysis chamber 102. The rotation of the rotating frame 201 agitates the material within the pyrolysis chamber 102, allowing for more uniform heating and ensuring that the heat conducted by the heat-conducting plate 103 is fully applied to the material, thus improving the efficiency and effectiveness of pyrolysis. During the pyrolysis process, an external gas delivery device is connected to the connection port 202 at the top of the rotating frame 201 via a flexible hose. The necessary gas delivered by the gas delivery device, such as inert gases (N2, Ar, CO2), maintains an oxygen-free environment to prevent material combustion. It enters the gas guide channel 203 through the connection port 202 and then diffuses evenly into all positions within the pyrolysis chamber 102 from the gas outlets 204 located around the side of the rotating frame 201, ensuring full contact between the material and the gas and further promoting the pyrolysis reaction. As the rotating frame 201 rotates, the rotating scraper... Because the rotating scraper 208 is nested and rotated on the side of the rotating frame 201 and abuts against the gas outlet 204, it moves relative to the rotating frame 201 as the rotating frame 201 rotates. Furthermore, because the transmission teeth b209 on the top of the rotating scraper 208 mesh with the annular retaining teeth 210 arranged around the inner wall of the pyrolysis chamber 102, the rotating frame 201 rotates, causing the rotating scraper 208 to rotate relative to the rotating frame 201. This promptly scrapes away any material residue that may accumulate around the gas outlet 204, preventing blockage and ensuring smooth gas discharge. Waste gas generated during pyrolysis is discharged from the furnace body 1 through the exhaust ports 104 arranged on the side of the furnace body 1, ensuring a stable gas environment within the pyrolysis chamber 102, which is beneficial for the continuous pyrolysis reaction. After pyrolysis is completed, the operable doors on the sides of the combustion chamber 101 and the pyrolysis chamber 102 are reopened for cleaning and maintenance of the furnace body 1, preparing for the next pyrolysis operation.
